  • Patent number: 10389564
    Abstract: The present invention is designed so that, in a radio communication system in which inter-terminal communication is carried out, the impact of inter-symbol interference due to the delay of inter-terminal discovery signals is reduced. The radio communication method of the present invention is used in a radio communication system in which each user terminal transmits the inter-terminal discovery signal in a transmission duration of a predetermined period. A radio base station determines the cyclic prefix (CP) length configuration for use in the transmission duration, and transmits cyclic prefix (CP) length configuration information which represents the CP length configuration. Each user terminal transmits the inter-terminal discovery signal based on the CP length configuration information.
